EMBROIDERING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 250,570, dated December 6, 18 81.

Application filed January 20, 1881. (ModeL) To all whom it may concern:

Be it known that I, CHARLESH. PALMER, of the city, county, and State of New York, have invented a new and useful Improvement in Embroidering Attachments for Sewing-Machines, which improvement is fully setforth in the following specification, reference being had to the accompanying drawings.

The object of my invention is to make a well- IO known embroidery-stitch, the same consisting of a succession of coils which the sewing-thread of the sewing-machine is made to interlace, and to accomplish which my invention requires a needle of the kind heroin more particularly described.

To this end my invention includes a presserfoot attachment which maybe applied to ordinary sewing-machines in place of the sewingmachine presser-foot, and has combined with it a horizontally-reciprocating needle with the eye at the point, and mechanism for operating the same by attaching this mechanism to the needle-bar of the sewing-machine, so that the embroidery-thread,which is carried bythe horizontal needle, is first worked by the latter in front of the sewing-needle, then moved laterally by a positive motion applied to the horizontal needle, that is thus thrown back of the sewing-needle during the ascent of the latter 0 and across its path, and subsequently returned laterally to its normal position by a spring attached to the stock of the embroidery-needle. The sewing-needle in its descent enters the loop of the embroidery-thread, which, by the action of the horizontal or embroidery needle in the line of the feed and its lateral action combined, coils the embroidery-thread around the sewing-needle.

In the accompanying drawings, Figure 1 rep- 0 resents afront elevation of the attachment during the ascent of the sewing-machine needle and the forward motion of the embroideryneedle, and Fig. 2 a plairthereof under similar conditions. v Fig. 3 is a plan of the embroid- 5 ery-needle.- Fig. 4 is a top view of a piece of fabric with the embroidery-stitch as produced thereon.

A is the bearing plate or shoe of the presserfoot, provided on its upper surface with a hori- 0 zontal slide, B, reciprocating in the line of feed.

G is the bed or table of the sewing-machine, and D the material to be embroidered. The slide B has attached to it in the rear, at c, a stout horizontal needle, E, (more clearly shown in Fig. 4,) for workingthe embroidery-thread d. 5 5 This needle has its eye a near its forward end, and a groove, 2, on its rear side back of said eye, connecting with eye 3 through which the embroidery-thread passes, and is curved in such manner that in the forward motion of the slide B the curved part of the needle E comes in contact with the front of the sewing-needle F during its upward motion, and carries the embroidery-thread d in front of the sewingneedle. The sewing-needle having completed its upward movement, in descending is made,

by proper adjustment of the embroidery-needle, to pass in its downward strokejust in the rear of the eye a and through the loop of the embroidery thread, the embroidery thread 7 making a loop around the sewing-needle and forming a coil, as shown in Fig. 4. This operation is repeated, and with each stitch of the sewing-needle a fresh loop is formed.

The horizontal action of the needle E in line of the feed is effected bya bell-crank lever, G, one arm of which is connected by a link, H, with the needle-barof the sewing-machine, and the other presses forward the slide B during the upward motion of the sewing-needle.

Upon the reverse movement of the lever G the slide B is drawn back by the action of a spring, 0.

The lateral movements of the embroideryneedle E are caused byitsimpingementagainst 8 the screw it, projecting in the longitudinal path thereof, said needle being held against said screw by the spring 0, attached to its stock.

I claim In an embroidering attachment, the needle E, curved 'nearits point, as shown, and provided with the eyes a and y and groove 2, in combination with mechanism for reciprocating said needle longitudinally and laterally, substantially as set forth.

CHARLES H. PALMER.
